My piping bags and tips are among my most valuable kitchen tools. It’s the only way to decorate cupcakes and of course my perfect sugar cookies.
I also use piping bags to fill and frost layer cakes, decorate cupcakes, for that gorgeous chocolate drizzle and to pipe finer details on cookies and cakes. Piping bags are also great for filling pastries.
When you’re just learning how to decorate cakes or cupcakes, filling the piping bag can be a little bit intimidating. But I am here to share all types of tips and tricks for How to Use A Piping Bag.
I’ve used hundreds and hundreds of piping bags, so I have lot of tips to share with you including my favorite products to use, how to use a coupler and how to clean a reusable bag.
How to fill a piping bag with frosting?
This can be tricky if you just have one hand, but you can do it! There’s two ways to do it. One way is to fold the bag over the top of your hand and the other is to fold the bag over a glass. Folding it over a glass is super helpful if you’re filling it with something pourable or hot like warm hot fudge.
In both methods, there’s a few helpful tips to make it easier on you to fill the piping bag whether it’s frosting or a glaze.
- First cut off the very tip (less than ½ and inch) of the bag to create a pocket for the air to escape. That way, when you press the frosting into the bag, there’s a place for the air to escape.
- Fold the bag at least halfway down over your hand (or a glass), ensuring the top edge is clear and folded all the way down so you can keep it clean.
- Use the side of your hand or the side of the glass to scrape the frosting off the spatula.
- Once the frosting is in the piping bag, use your spatula to further press the frosting down into the bag.
- Once the bag is halfway filled, pick it up and give it a solid shake to help further settle the frosting in the bag.
- Once your piping bag is filled use the side of your hand or a rolling pin to press all the frosting down in the bag. like to use rubber icing bag ties to keep my bags closed.
Commonly asked question about how to use a piping bag:
What size do piping bag do I need?
Piping bags come in many different sizes and are sold in qtys of 12, 25, 50 or 100 packs.
The smallest size I recommend using is a 12-inch bag. They work great for getting that nice and fine drizzle of chocolate over cookies or a slice of cake. They’re also great for writing letters on cakes, piping finer details with buttercream and for decorating cookies with royal icing.
You can often find the 12-inch piping bags at craft stores like Michaels or Joann Fabrics. I buy them in rolls of 100, and my preferred brand for this is Daymark. They are very durable and come in rolls, so it’s easy to use and store.
The largest size I use is an 18-inch bag and it’s the most common size I use. They’re great for frosting cupcakes and cakes because they hold a lot of frosting, so you may only need one bag. I hate refilling bags! I also buy the Daymark bags in 100 packs, but you can easily find them in 12-packs. If you can’t find 18-inch bags, 16-inch piping bags will also work.
How much do you fill a piping bag?
It’s best to fill 1/2 to 2/3 full depending on what you’re filling it with. Refilling a bag is not as easy the second time around and it can be a little messy. However, if your piping bag is too full, it will make it difficult to use, especially if your frosting is thick.
If you are working with large batches of frosting, I recommend filling two separate piping bags and then using a third bag fitted with the tip in it. Once you get through the first bag, pull it out and drop in the second bag in.
How to use a piping bag with a coupler:
A coupler is two pieces of plastic (similar to a nut and bolt) that is used together with a piping bag so you can seamlessly change the piping tips. It also secures the piping tip to the bag. Have you ever had a piping bag explode and shoot off the tip? I have and it’s not fun.
- The trick is to cut the bag only enough so that the coupler fit through the opening, but high enough that it doesn’t inter fear with your piping tip.
- Drop the larger piece into the piping bag, then fit the piping tip over the top (so that the bag and the coupler are inside the piping tip. This helps secure the piping bag in place.
- Then take the smaller piece and slide it over the tip, screwing it onto the plastic piece. You can see the bag is secured inside the coupler.
To remove the coupler from your bag when you done, cut the piping bag 1 inch above the top of the coupler and flip it inside out. Also running it under hot water will help to loosen it up.
How to use a piping bag without a coupler:
You will cut off the tip of the bag just high enough so that it does not interfere with the actual piping tip.
If you cut the piping bag too high up, you might find that with the pressure of squeezing the bag, the frosting tip will pop out, so don’t cut it up higher than you need it.
Sometimes if I don’t want to commit using just one piping tip, I use a double bag method. I fill one piping bag with frosting and cut off the end. Then I drop it into another bag that is fitted with a tip. This allows me to use the same color interchangeably. However, you have to cut the inside bag up high enough so it doesn’t hang out of your piping bag. See below? This interior bag is too long, it’s coming out of the tip and that won’t work!
How do you change piping tips?
If you are using a piping bag with a coupler, it’s super easy! Just unscrew the outer plastic piece, pop you tip off, and replace it with a new tip, then screw the top back on. This is the fastest way to do it if you want to use the same color with different tips.
How do you frost cupcakes with a piping bag?
It can depend on how you’re intending to frosting your cupcake, but generally speaking, you want to hold the bag at a 90 degree angle over top of your cupcake and working from the outside edge in.
Luckily for you, I have a whole tutorial on how to decorate the perfect cupcake.
Are piping bags reusable? How do you clean a piping bag?
If you are using disposable bags filled with frosting, I wouldn’t go to the trouble to clean them out, that is why they’re disposable. Plus they’re greasy from the frosting. Occasionally I will clean them and reuse them, rinse with hot soapy water. Then I flip them inside out and put them in my drying rack to dry completely.
However, the are reusable piping bags, often referred to as featherweight decorating bags or pastry bags which are made from polyester. They can be cleaned with hot soapy water as well. I find it’s helpful to flip it inside out to clean it, and ensure it’s completely dry before restoring.
How do you use a Ziploc bag as a piping tip?
If you’re out of piping bags, then you can use a plastic Ziploc bag. However, they are not nearly as strong, and if they are over filled or you squeeze with too much pressure, it’s likely that the piping tip will fall out.
